  • the initial force required to begin to move the plunger down is sufficiently great compared with the force required when the air and/or liquid begins discharging from the nozzle so that the user cannot easily terminate or slow down the stroke before the bottom of the stroke is reached.
  • the full stroke quantity of fluid will be discharged from the pump at a flow rate that will be sufficient to provide the desired fine mist atomization.
  • the stroke length is relatively short, the overall height of the pump can be reduced, and shorter pump components can be employed.

Also, the liner 43 may be combined with the turret 38 as a unitary structure. In addition, the novel system of the present invention accommodates the use of insert components which can be readily fabricated and relatively easily assembled.

  • the pump 20E can have a greater height without increasing the length of the piston 82E per se or the length of the actuation button 81 per se.
  • the pump 20E also employs a modified design for the location of the upper end of a dip tube 30E.
  • the upper end of the dip tube 30E is located near the bottom of the pump body 48E and is disposed within a hollow post or sleeve 49E which extends downwardly around the upper, distal end of the dip tube 30E.

  • the plunger skirt 69F also defines an internal shoulder 75F for receiving the upper end of a compression spring 100F.
  • the lower end of the compression spring 100F rests against the upper surface of the cap flange 34F. This normally biases the plunger 7IF upwardly to a fully elevated, rest position as shown in FIG. 17.
  • the plunger skirt bead 73F engages the cap outer wall bead 35F, and this prevents any further upward movement of the plunger 71F. Additionally, when the plunger 7IF is in the fully elevated, unactuated rest position illustrated in FIG. 17, there is a gas-tight seal between the cap wall bead 35F and the plunger skirt bead 73F.

  • the hollow post 114F has an annular bead 113F for retaining the valve member 110F during assembly.
  • the post 114F and the valve member 11OF are sufficiently resilient to accommodate movement of the valve member bead 115F past the post bead 113F during assembly.
  • the hollow post 114F defines a vent groove 11IF on the exterior surface of the post. This reduces the amount of air that is trapped and compressed inside the valve member 110F during assembly.
  • the valve member 110F includes an engaging bump or post 124F projecting downwardly from the frustoconical sealing surface 122F. When the valve member 110F is in the fully closed position as illustrated in FIG. 17, the engaging post 124F projects into the discharge orifice 86F.
  • valve member 110F continues downward movement of the plunger 7IF causes the pressure within the pump chamber to build up sufficiently to force the valve member 110F upwardly away from the valve seat 12OF around the discharge orifice 86F when the force of the valve spring 118F is overcome.
  • the valve member 110F is in the fully closed position, as illustrated in FIG. 17, only the portion of the valve member 110F that projects inwardly (downwardly) from the valve seat 12OF is exposed to the increasing pressure in the pump chamber.
  • the area of the valve member 110F exposed to the valve chamber pressure when the valve member is in the closed position may be characterized as a "first pressurizable area" or "first area,” and it is a relatively small area.
  • valve member 110F moves quickly to the fully open position as illustrated in FIG. 18, communication is established between the pressure chamber and the discharge passage which includes the cavity 102F. Because the valve member 110F moves quickly to its fully open position in the discharge cavity 102F, the maximum volume of the discharge passage is substantially instantaneously placed in communication with the pressure chamber (which is the volume between the closed seat 50F of the check valve ball 94F and the orifice 86F) . The pressurized liquid from the pressure chamber can then flow rapidly through the fully opened orifice 86F, past the valve seat 120F, and through the maximum volume of the discharge passage which includes the button cavity 102F and nozzle 103F.
  • valve member 110F Because the large surface area at the upstream (lower) distal end of the open valve member 110F is subjected to the fluid pressure, the valve member 110F is held by the pressure at the full open position (FIG. 18) . This is in contrast with certain conventional designs wherein a valve must be held away from a valve seat by the friction loss forces or velocity head forces of the fluid flowing past the valve member.
  • the reduced resistance to liquid flow past the fully opened valve member 110F results in a relatively high discharge rate of liquid from the pressure chamber through the button discharge passage. This provides the desired fine mist spray and permits the plunger 7IF to move rapidly to the bottom of the stroke.
  • the operator senses that the pump seems to have an initial, momentary resistance to plunger actuation which is followed by a relatively low resistance.
  • the initial, higher force supplied by the operator causes the operator's finger to continue moving—with the initially applied high force and at a high rate of speed—against the actuator until the plunger reaches the end of the compression stroke.
  • the compression stroke is sufficiently short, and the initial resistance is sufficiently high, so that the operator normally cannot, even if he tries, release his finger pressure fast enough to effect only a partial compression stroke or to effect the compression stroke at a slow rate.
  • the stroke is completed at a sufficiently high rate of speed to provide at least the minimum liquid discharge flow rate that is necessary to produce the desired volume of spray and the desired degree of atomization.
  • valve member first pressurizable area the second pressurizable area, and the associated biasing spring 118F may be characterized as a "releasable holding means" for holding the valve member in the closed position when the chamber pressure is less than the predetermined pressure and for permitting the chamber pressure to urge the valve member to an open position with a substantially instantaneously increased net pressure force on the valve member when the chamber pressure is at least equal to the predetermined pressure.
  • the plunger cross wall 83F engages the distal end cross wall 61F of the stationary piston 53F.
  • the spring 100F is substantially fully compressed. Preferably, this results in a minimum of "dead" space or volume.
  • the plunger cross wall 83F moves upwardly away from the stationary piston post 65F. This permits the valve seat 12OF to be engaged by the valve member 110F which is biased downwardly by the spring 118F. The valve member 110F then remains held by the biasing spring 118F in sealing engagement against the valve seat 12OF as the plunger returns to the fully elevated position (FIG. 17) .
  • the liquid in the container is under atmospheric pressure.
  • the difference between the atmospheric pressure on the liquid in the container and the reduced pressure under the plunger cross wall 83F around the non-return ball 94F defines a pressure differential. This imposes a lifting force on the liquid which drives the liquid up the dip tube 3OF and lifts the check valve ball 94F.
  • the liquid can then flow through valve seat 5OF and into the pump chamber between the plunger cross wall 83F and piston valve seat 50F.
  • the pump chamber When a new pump is initially assembled on a container of liquid and provided to a user, the pump chamber typically contains only air.
  • the chamber must be primed with liquid from the container. This requires removal of much of the air in the chamber and replacement of that air with liquid from the container. This can be accomplished by depressing and then releasing the plunger 71F a number of times. When the plunger 7IF is fully depressed, the air in the chamber is compressed. Because air is so highly compressible, the initial increase in pressure within the chamber may not be sufficient to overcome the biasing force of the spring 118F which holds the valve member 110F closed.
  • valve member protrusion 124F engages the post 65F on the cross wall 61F of the stationary piston 53F, and this causes the valve member llOF to be held away from the valve seat 120F. This opens the discharge orifice 86F and permits some of the slightly pressurized air to discharge through the insert nozzle 103F.
  • the plunger 7IF When the plunger 7IF is next released, it is returned to the fully elevated position by the main spring 100F. This increases the volume of the chamber and lowers the pressure so that liquid from the container is forced by the pressure differential part way up the dip tube 30.
  • the operator subjects the plunger 7IF to a number of such depression and release cycles. With each cycle more air is discharged from the chamber, and more liquid flows up the dip tube and eventually into the chamber. When sufficient liquid is present in the chamber, the subsequent actuations result in a discharge of the liquid as an atomized spray. It will be appreciated that the novel structure of the pump and valve system permits the pump to be actuated with a relatively short stroke.

Abstract

L'invention concerne une soupape de débit pour une pompe (20, 20F) pouvant être actionnée avec le doigt avec un piston d'actionnement (80, 71F et 69F). Ce piston définit un passage de débit (86, 102, 104 ou 86F et 104F) en communication avec l'atmosphère ambiante. La soupape de débit comprend un siège (120, 120F) de soupape défini par le piston dans le passage de débit. Un élément de soupape (110, 110F) est placé dans le passage de décharge et peut se déplacer (a) en amont, vers une position fermée contre le siège de soupape, dans laquelle l'élément de soupape définit une première zone soumise à la pression de la chambre, et (b) en aval, vers une position ouverte s'éloignant du siège de soupape, dans laquelle l'élément de soupape définit une deuxième zone soumise à la pression de la chambre de telle sorte que la force de pression nette imposée sur l'élément de soupape par la pression de la chambre est plus importante lorsque l'élément de soupape est ouvert que lorsque cet élément est fermé. Un ressort (118, 118F) solicite l'élément de valve en direction du siège de soupape.
